Abstract
There is provided the use of a crystal growth inhibitor for reducing the fabric abrasion occurring upon laundering treatment.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A method for reducing fabric abrasion, which comprises the steps of contacting the fabrics with a crystal growth inhibitor wherein said crystal inhibitor is selected from glycolic acid, phytic acid, oxydisuccinate, mellitic acid, succinic acid, oxydisuccinic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, ether hydroxypolycarboxylates, organic diphosphonic acid, and mixtures thereof.
2. A method according to claim 1 , wherein said carboxylic compound is glycolic acid.
3. A method according to claim 1 , wherein said organo diphosphonic acid is hydroxy-ethane 1,1 diphosphonic acid.
4. A method according to claim 3 , wherein said crystal growth inhibitor is incorporated into compositions at a level off than 10%.
5. A method according to claim 4 , wherein said crystal growth inhibitor is incorporated into compositions at a level from about 0.05% to about 0.25%.
6. A method according to claim 4 , wherein said composition is selected from pre- or post wash additives, laundry compositions, rinsing compositions of a laundry process, rinse added fabric softener compositions, and dryer added compositions.Cited by (0)
